Q is an arm of toggle-arm in connection with the arm of the the lever, to whose free end is attached a cord lever by means of which the door is thrown or chain, R, passing through a hearing at S. up to open the pressure-chamber.

From the point S the cord passes but my invention is equally applicable to stato an eye, T, upon the door U, (the cord passtionary presses. I a ing through said eye.) The door is hinged to C is the traverser by which the material is thepress-box at u.

On the ing thrown outward by springs 12, to engage backward movement of the traverser the hay. beneath fixed catches W at the sides of the or other material is prevented from following feed-opening of the press-box. As illustrated the traverser in its retrograde movement by in the drawings, the spring-catchesV turn ona 50 automatic retainers F, whosepoints f project pivot,r,and havearmsV,to which the springs through the sides of. the boxinto thechamber are attached at one end, the other ends of the springs being made fast to the press-box. The cord or chain R divides into two branches, 1", which are made fast to the arms V.

The operation of my improvement is as follows: When thesweep is intheposition shown in Figs. 1 and 2 of the drawings, the traverser is in its most advanced position. When the sweep commences to swing around, the cam J acts on the lever Q by meansof intermediate mechanism, as described, to draw back the cord R. The first action ot'the cord is to throw out the catches V from beneath the fixed catches W. The cord then draws the door upward into the position shown in I ig. 3, opening the pressure-chamber for the introduction of a charge of hay, the traverscr having been simultaneously drawn back from said cham-- her. As the door reaches its open position (see Fig. 3) the movement of the toggle-arm carriesthe cam Joutof contact with the downturned end of the arm Q, and the sweep continues to more until the traverser has reached its backward position. (See Fig.3.) A charge of hay is then fed into the pressurechamber D. The door U is then thrown shut by hand, the catches engaging automatically and holding the door shut while the hay is under pressure and until the traverser begins to move backward.

In place of the arm Q a wheel or sector may be used, which is grooved at the periphery to receive the cord or chain R, which is thus operated by the oscillation of the wheel or seetor. A crank disk or wheel may be used in place of the arm Q.

I claim- 1. In a continuous baling-press, a door, U, connected to the sweep by means shown, and

opened by the movement of the sweep, sub-V .stantially as set forth.
